Splicing to orchestrate cell fate.

Alternative splicing (AS) plays a critical role in gene expression by generating protein diversity from single genes. This review provides an overview of the role of AS in regulating cell fate, focusing on its involvement in processes such as cell proliferation, differentiation, apoptosis, and tumorigenesis. We explore how AS influences the cell cycle, particularly its impact on key stages like G1, S, and G2/M.

Gold nanorod-based engineered nanogels for cascade-amplifying photothermo-enzymatic synergistic therapy.

Reactive oxygen species (ROS)-mediated anticancer modalities, which disturb the redox balance of cancer cells through multi-pathway simulations, hold great promise for effective cancer management. Among these, cooperative physical and biochemical activation strategies have attracted increasing attention because of their spatiotemporal controllability, low toxicity, and high therapeutic efficacy. Herein, we demonstrate a nanogel complex as a multilevel ROS-producing system by integrating chloroperoxidase (CPO) into gold nanorod (AuNR)-based nanogels (ANGs) for cascade-amplifying photothermal-enzymatic synergistic tumor therapy.

NIR-II photo-accelerated polymer nanoparticles boost tumor immunotherapy via PD-L1 silencing and immunogenic cell death.

Immune checkpoint blockade (ICB) therapy is a widely favored anti-tumor treatment, but it shows limited response to non-immunogenic "cold" tumors and suffers from drug resistance. Photodynamic therapy (PDT), as a powerful localized treatment approach, can convert a "cold tumor" into a "hot tumor" by inducing immunogenic cell death (ICD) in tumor cells, thereby enhancing tumor immunogenicity and promoting tumor immunotherapy. However, the effectiveness of PDT is largely hindered by the limited penetration depth into tumor tissues.

Injection of ROS-Responsive Hydrogel Loaded with IL-1β-targeted nanobody for ameliorating myocardial infarction.

The cardiac microenvironment profoundly restricts the efficacy of myocardial regeneration tactics for the treatment of myocardial infarction (MI). A prospective approach for MI therapeutics encompasses the combined strategy of scavenging reactive oxygen species (ROS) to alleviate oxidative stress injury and facilitating macrophage polarization towards the regenerative M2 phenotype. In this investigation, we fabricated a ROS-sensitive hydrogel engineered to deliver our previously engineered IL-1β-VHH for myocardial restoration.

MSAB limits osteoarthritis development and progression through inhibition of β-catenin-DDR2 signaling.

The aberrant activation of the canonical Wnt/β-catenin signaling has been identified as a significant contributor to the pathogenesis of osteoarthritis (OA), exacerbating OA symptoms and driving OA progression. Despite its potential as a therapeutic target, clinical translation is impeded by the lack of a targeting delivery system and effective drug candidate that can modulate steady-state protein levels of β-catenin at post-translational level. Our study addresses these challenges by offering a new approach for OA treatment.

Compensatory effect-based oxidative stress management microneedle for psoriasis treatment.

Reactive oxygen species (ROS) at elevated levels trigger oxidative DNA damage, which is a significant factor in psoriasis exacerbation. However, normal ROS levels are essential for cell signaling, cell growth regulation, differentiation, and immune responses. To address this, we developed ROS control strategies inspired by compensatory effects.

The pathogenesis and management of heatstroke and heatstroke-induced lung injury.

In the past two decades, record-breaking heat waves have caused an increasing number of heat-related deaths, including heatstroke, globally. Heatstroke is a life-threatening systemic condition characterized by a core body temperature >40°C and the subsequent development of multiple organ dysfunction syndrome. Lung injury is a well-documented complication of heatstroke and is usually the secondary cause of patient death.

Lipopolysaccharide-induced active telocyte exosomes alleviate lipopolysaccharide-induced vascular barrier disruption and acute lung injury via the activation of the miRNA-146a-5p/caspase-3 signaling pathway in endothelial cells.

Background: Lipopolysaccharide (LPS)-induced apoptosis of lung microvascular endothelial cells (ECs) is the main reason of lung edema and acute lung injury (ALI) in septic conditions. Telocytes (TCs) are a distinct type of interstitial cells found around the lung microvasculature, which may protect ECs through the release of shed vesicles. However, whether TCs protect against LPS-induced EC apoptosis and ALI has not been determined.

Photosynthetic Bacteria: Light-Responsive Biomaterials for Anti-Tumor Photodynamic Therapy.

Photodynamic therapy (PDT) is a promising noninvasive tumor treatment modality that relies on generating reactive oxygen species (ROS) and requires an adequate oxygen supply to the target tissue. However, hypoxia is a common feature of solid tumors and profoundly restricts the anti-tumor efficacy of PDT. In recent years, scholars have focused on exploring nanomaterial-based strategies for oxygen supplementation and integrating non-oxygen-consuming treatment approaches to overcome the hypoxic limitations of PDT.

The relationship between fractional amplitude of low-frequency fluctuations (fALFF) and the severity of neglect in patients with unilateral spatial neglect (USN) after stroke: A functional near-infrared spectroscopy study.

Objective: Unilateral spatial neglect (USN) following right hemisphere stroke is more pronounced, severe, and persistent than in the left hemisphere. However, the pathophysiological mechanisms underlying USN remain largely unknown. This study aims to investigate the relationship between the fractional amplitude of low-frequency fluctuations (fALFF) in the right hemisphere of patients with post-stroke USN and the severity of neglect using resting-state functional near-infrared spectroscopy (fNIRS) technology.

In this study, tumor-bearing mice engaged in voluntary wheel running exhibited a notable decrease in tumor growth, exceeding 30%.

Economic cost of not meeting the 24-h movement guidelines in china: Research gaps and recommendations.

It is well-known that not meeting the movement guidelines, including insufficient physical activity (PA), excessive sedentary behavior (SB), inadequate sleep duration, and their combinations, are independent risk factors for noncommunicable diseases (NCDs). The prevalence of not meeting the guidelines is high across the world, especially in China where has one of the largest population. Some studies have estimated the economic cost of insufficient PA in China, which is useful to guide policymakers to develop and implement effective health actions.

Revisiting the drivers of electricity consumption in designated Sub-Saharan African regions: Unraveling the role of education.

It has been established that steady supply of energy to various sectors of the economy is critical for societal growth and development. According to recent figures, barely one-third of the whole population in Sub-Saharan Africa has access to electricity, making the region the poorest in the world in terms of access to electrical power today. This stands in stark contrast to the vast energy resources that could be utilized to provide the necessary energy.
